I grabbed some of the rtl-sdr Metal usb stick cases when they were in stock recently.
I figured I’d stick the innards from a couple of my FlightAware Orange and RadarBox sdrs in aluminum enclosures with silicone heat transfer pads.
The enclosures come with the standard rtl-sdr v3 labeling, so I sanded it off to avoid confusing them with my real rtl-sdrs.
Then I wasn’t sure if I liked the sanded raw look(similar to the stock anodized look), and wondered what they’d look like polished.
So grabbed some Mag Polish and threw a buff disc on my palm sander and went to town.
I like both looks so have a mix.
I had to trim the casing down for the RadarBox(hacksaw and file).
The Thermal Pad I used is 2mm silicone.
2.5mm would be ideal, and maybe 3mm even could be jammed in there, but if you use the rails in the enclosure for the circuit board it is pretty awkward to try and slide the pad and board in
I may coat the polished one with jewelry sealant to keep it shiny.
